Abstract

Un método para la preparación de una membrana de filtración. El método incluye proporcionar una solución de copolímero a través de la disolución de un copolímero estadístico en una mezcla de un codisolvente y un primer disolvente orgánico, recubrir la solución de copolímero sobre una capa de soporte porosa para formar una capa polimérica sobre la misma, coagular la capa polimérica en la parte superior de la capa de soporte para formar una membrana de material compuesto de película delgada, y la inmersión de la membrana de material compuesto de película delgada en un baño de agua con el fin de obtener una membrana de filtración. También se divulga una membrana de filtración que se prepara por medio del método, y un proceso de filtración de un líquido a través del uso de la membrana de filtración que se prepara de esta manera.
